The MAHLE Motorsport PowerPak Plus Nissan Skyline GT-R pistons are designed for all-out power, performance and durability. By partnering with some of the best GT-R builders in the business, MAHLE’s PowerPak Plus pistons are being proven on the track reaching record breaking milestones for the Skyline GT-R including the current quickest and fastest ¼-mile, and the fastest standing ½-mile record.
MAHLE’s participation in these partnerships have allowed the PowerPak Plus pistons to evolve into the best shelf stocked GT-R pistons available, capable of handling power levels in excess of 1,500 horsepower with ease and has endured power output over 2,700 wheel horsepower with boost pressures exceeding 65 psi.
The GT-R PowerPak Plus pistons start the production process with an ultra-strong, low drag, lightweight, 2618 alloy MAHLE slipper skirt forging. The forging is precision machined to exacting tolerances on purpose built equipment manufactured by MAHLE specifically designed for piston production. The pistons are then coated with a phosphate dry lubricant to guard against galling in the pin bores and add lubricity in the second and third ring grooves. The top ring groove is hard anodized to protect against micro-welding insuring optimum ring seal over the life of the engine. And finally the piston skirts are treated with MAHLE’s proprietary Grafal anti-friction coating. In addition to lowering frictional drag Grafal has a cushioning property that greatly reduces wear for both the piston and the bore as well as a substantial reduction in noise.
For the Nissan Skyline GT-R to perform to its full potential, every component in the engine needs to as well. The MAHLE Motorsport PowerPak Plus piston kit has countless hours of R&D testing behind them to support high load.
